As the pioneer of smart contracts and decentralized applications (dApps), Ethereum is experiencing a significant technological leap. The highly anticipated Cancun-Deneb upgrade (codenamed Dencun) signals a qualitative breakthrough in network scalability and operational efficiency. At the core of this upgrade, EIP-4844 introduces Proto-Danksharding technology, bringing unprecedented expectations to the Ethereum community. So, how will this revolutionary technology truly change Ethereum’s future? This article will delve into the core mechanisms of the Dencun upgrade and its profound significance for traders and developers.

Dencun: A Key Milestone on the Ethereum 2.0 Roadmap

The Cancun-Deneb upgrade (commonly referred to as Dencun) represents a strategic shift in Ethereum’s scalability and operational efficiency. Its name derives from the bright star Deneb in Cygnus, symbolizing the network’s leap toward higher performance. In Ethereum 2.0’s grand blueprint, this upgrade plays a crucial role in improving scalability, enhancing security, and optimizing overall performance. The Cancun phase focuses on innovations in the data availability layer, while Deneb involves deep modifications to the consensus layer.

The Revolutionary Breakthrough of Proto-Danksharding and EIP-4844

EIP-4844 (Proto-Danksharding) is the technological driver of the Dencun upgrade, fundamentally redefining data storage methods. The proposal introduces the concept of “blobs”—a new data packaging mechanism that optimizes data storage and processing workflows, significantly increasing Ethereum’s information capacity.

Proto-Danksharding is not just an independent feature but also a necessary step toward full Danksharding, aiming to lay the technical foundation for Ethereum’s comprehensive expansion. The upgrade also includes the State Expiry feature, which periodically cleans outdated data and redundant information, reducing on-chain burden and boosting network efficiency.

The rollout of Proto-Danksharding will inevitably impact the Data Availability (DA) layer ecosystem, including emerging projects like Celestia, EigenDA, and Avail. These DA layers provide scalable data infrastructure for Ethereum Layer-2 solutions, and the deployment of Proto-Danksharding is expected to significantly lower data access costs, making such networks more economically feasible.

Other Key EIPs in the Dencun Upgrade

Dencun encompasses several technical improvement proposals that developers should pay close attention to:

1. EIP-1153: Introduces new opcodes for temporary data storage during smart contract execution. This improvement is expected to directly reduce gas costs and improve network processing efficiency.

2. EIP-4788: Enhances interoperability of Ethereum’s consensus layer by introducing a Beacon Block Root anchoring mechanism, enabling Layer-2 to access consensus data more directly.

3. EIP-5656: Adds the MCOPY opcode, optimizing memory data copying during smart contract execution.

4. EIP-6493: Fine-tunes validator block selection mechanisms, improving finality and reducing mining centralization.

5. EIP-6780: Limits the scope of the SELFDESTRUCT function, significantly enhancing the security of smart contracts and the network.

Review of the Upgrade Timeline and Progress

In early 2024, Ethereum entered the full testing phase of Dencun. On January 17, the Goerli testnet first integrated the upgrade; on January 30, Sepolia followed; and on February 7, Holesky completed adaptation. The upgrade was officially deployed on the mainnet on March 13.

Notably, this upgrade was originally scheduled for Q4 2023 but was delayed to Q1 2024 following discussions at the November Core Developers consensus meeting.

Practical Value of the Dencun Upgrade

The Dencun upgrade marks a firm step toward a more efficient, secure, and sustainable Ethereum. Its core significance is reflected in multiple dimensions:

Order-of-Magnitude Increase in Network Capacity
Proto-Danksharding combined with blobs mechanism significantly boosts transaction processing speed and data throughput.

Fundamental Reduction in Gas Fees
Deployment of EIP-4844 directly targets Layer-2 cost bottlenecks, with expected reductions in gas fees by 10 to 100 times. This is the central promise of Dencun and the change users are most期待。

Leap in Ethereum’s Throughput
With more advanced transaction processing mechanisms and higher network bandwidth utilization, Ethereum’s TPS is projected to jump from around 15 to 1000 TPS.

Strengthening Security Framework
Proposals like EIP-6780 restrict dangerous operations and incorporate modern cryptography, building a more robust network defense.

Innovation in Data Storage Capabilities
Dencun leverages sharding technology to partition the network into finer processing units, dramatically expanding blockchain data capacity.

Transformative Changes in Layer-2 Networks

Layer-2 solutions are designed to process transactions off the main chain and batch-settle results onto Ethereum’s mainnet. According to Fidelity research, Layer-2 fees currently account for about 10% of total Layer-1 costs, but this ratio is expected to decrease significantly after the upgrade.

Currently, transferring ETH to Arbitrum, Optimism, and Polygon costs approximately $0.24, $0.47, and $0.78 respectively, while token swap fees are $0.67, $0.92, and $2.85. Post-Dencun, these figures are expected to improve markedly.

Specific impacts on Layer-2 include:

Seamless Protocol Interoperability
Interactions between Layer-2 and the mainnet will become more efficient, drastically reducing cross-layer transaction costs and improving user experience.

Capacity Doubling
The efficiency gains on the mainnet will have spillover effects benefiting all Layer-2 solutions. Final transaction confirmation speeds will increase, and fees will further decrease.

Unified Security Standards
New security norms and best practices introduced by Dencun will gradually be adopted across Layer-2 ecosystems, creating a more stable and reliable transaction environment.

Deep Impact on Users and Developers

As a crucial phase toward full Danksharding and a key part of the Ethereum 2.0 roadmap, Dencun is poised to bring transformative changes to the ecosystem:

Dual Enhancement of Transaction Speed and Security
Post-upgrade, Ethereum’s throughput is expected to soar from about 15 TPS to 1000 TPS, while the proof-of-stake mechanism ensures network security. Faster transactions mean users can operate assets more swiftly, and improved security alleviates concerns.

Strengthening and Prosperity of the dApp Ecosystem
With increased network capacity and processing efficiency, developers will have a more stable environment to deploy complex decentralized applications. Large-scale, high-complexity dApps will no longer be hindered by network congestion, enriching the ecosystem’s diversity.

Emergence of Innovative Applications
The blobs storage mechanism (providing 1 MB bandwidth per slot) introduced by Dencun opens new possibilities for developers. Easier data storage and retrieval capabilities will encourage exploration of unprecedented application scenarios, driving ecosystem innovation.
